BSA motorcycle

This is an old BSA I took in trade years ago it is 90 percent complete I don't know much about these motorcycles so my info may not be accurate I believe it a 1964 441 I believe it's all original I did ride it from where I got it about 10 miles but it has an oil leak I believe from a pump seal but it did run and pull good it's pretty clean its missing the battery cover and some other small parts but overall in pretty good cond email me with any questions and I will answer them to my best ability in the state of Georgia a vehicle this old does not require a title so all I have is a bill of sale on this motorcycle
